Hemianthus callitrichoides also is a very easy plant to grow like this.
The one on top is Bog pimpernel (might find it in a pondshop)..
Depending on the shape of the wood many plant can be grown against it. As long as the roots are in the water and the emersed plant part can take the lower humidity. This is a horizontal piece of wood with a hollow cavity, it has among other mainly Lilaeopsis brasiliensis on it.
If you tie plants to wood than for example make a combination of plants, one submersed like an Anubias close to the surface. This plant will attach it's roots to the wood and Anubias grows an extensive rootsystem, it grows more roots than leaves.
Use it.. And than take a plant you like to grow emersed and tie this together with the anubias on top and the other plants roots under the anubias root. The anubias will attach and support the emersed plant. Even later you can stick another plant with the tweezers behind the anubias roots.
They will knot and lock together.
Here you see such a setup, also with Hydrocotyl tripatitty.. If you look closely you see an (medium sized) Anubias leave emeresed and also some submersed, it is tied to the backside of the wood, not as focal point but as anchor. The Carex (grassy plant) in the midlle and the Hygrophilla are growing in the anubias roots.. The hygrophila is in trouble, i did put it there myself in that condition, it was dying in a wabi kusa. It will come back and already is forming new growth. In the back you see a Pogostemong stellatus. In this tank it is actualy in the substrate, but i know it will work with this one too. Becaue i already did it in another tank.
Anyway, just give the plant it's support it needs and the choices are numerous.
Start a new hobby called Wabi Kusa, with this you'll find which plants do good in lower humidity.. And if you've growen some WK plants it's easily to be transfered to grow above an aqaurium.
